My woodstove's smoke pipe has 13 joints in it before entering the
chimney, could this thin wall steel be miged or would tig be a must.
Is there any other way to seal these joints? When it is very windy out
I get small rings of smoke puffing out of each joint, the flue is
above my peak, I have tried with /withought the rain cap and I now
have a "whirlybird" on top which is suposed to aim downwind and cause
a venturi to aid in draft but I am still getting the back draft. Also
it only seems to happen when I have the combustion air inlet is turned
down low. Thanks for any help.
